+==== Something Quirky with this OLED Screen ====
+\\
+So I have noticed something a little quirky with this LCD Panel. It seems to be in two parts, let me explain.
+\\
+\\
+The Yellow section of the panel is 16 pixels high, then there seems to be a hard barrier between there and the Blue section which is 48 pixels high.
+\\
+\\
+{{ :64x128-oled-screen-split.png?200 |}}
+\\
+So you can move text vertically up and down the screen, but not through the join in the yellow/blue part, the text will get chopped off. So you will have to think about the screen as two parts.
+\\
+\\
+Below is some code where you can squeeze 8 lines of text on to this little OLED. Each line the text is 6 pixels tall, and there is a two pixel gap between each line. Effectively each line takes 8 pixels, so 8 lines = 8linex8Pixel = 64 pixels, the exact LCD height.
+<code:python | download>
+from machine import Pin, I2C
+import ssd1306
+import time
+i2c = I2C(0, scl=Pin(5), sda=Pin(4), freq=200000)
+lcd = ssd1306.SSD1306_I2C(128, 64, i2c)
+lcd.fill(0)
+lcd.text("Yo Tuesday Club!", 0, 0)
+lcd.text("SSD1306 LCD",      0, 8)
+lcd.text("Address 0x3C",     0, 16)
+lcd.text("Cool :)",          0, 24)
+lcd.text("Another Line :)",  0, 32)
+lcd.text("One More? :)",     0, 40)
+lcd.text("Line 7",           0, 48)
+lcd.text("Line 8",           0, 56)
+lcd.show()
+time.sleep(300)
+lcd.fill(0)
+lcd.show()
+</code>
+The LCD can have 16 characters across, so the characters are 8 pixels wide. So 16char x 8pixel =128 Pixels wide.
+\\
+\\
+Using the code above, feel free to change the text and have a play, also play with the line spacing to explore the Yellow/Blue section limitation, each line is moved down by 8 pixels in the script, but have a play with these values to see what fits for you.
